The emergency consultation of a female patient revealed a left-sided prolapse of the eyeball with visual loss. The patient had fallen against an object hitting the left eye 40 min prior to the consultation. Motility of the eye was severely restricted and retinoscopy was impossible due to a corneal edema. The pupil was moderately dilated and non-reactive. The ocular pressure was 50 mmHg. Spontaneous repositioning was unsuccessful and an immediate lateral canthotomy was performed. The follow-up control showed that the patient had recovered good visual acuity with a reduction of intraocular pressure and pain. The latest findings were uneventful.
